When conducting high-level interviews with stakeholders of a project, what are the key questions that should be asked?

1. A. How much usable storage are you looking for?What client OS will access this storage?Which applications will access this storage?
2. B. Which backup application is in use today?What is your change rate?How many clients will connect to the cluster?
3. C. What does your network architecture look likeDo you have existing NAS infrastructure?Do you have 10Gb or 1GbWhich applications will access this storage?
4. D. Who are the application owners?How much usable storage is needed?What applications will be accessing the storage?How many users are in your Active Directory?

Correct Answer: A

What does Isilon OneFS use to re-write data when a disk read fails?

1. A. Dynamic Sector Repair
2. B. NVRAM
3. C. Isilon Data Integrity
4. D. CRC

Correct Answer: A

You have 1000 users for an application that reads and writes files averaging between one and four MB in size. Each user requires 24 MB of RAM. You want to add another 1000 users for this application, and in preparation for them, you run the isi statistics command. You discover that the average CPU utilization is 20%; aggregate throughput averages 700 MB/s and the disk QueueD average is 1.5. Your cluster currently has five X200 (12 GB RAM, 1 TB drive) nodes, uses N+2:1 protection and 1 GigE networking.
What should you do to accommodate the next 1000 users?

1. A. Add five additional X200 (12 GB, 1 TB drive) nodes
2. B. Upgrade each X200 node to a total of 24 GB of RAM.
3. C. Upgrade two of the 1 GigE NICs to 10 GigE on each node.
4. D. Add five A100 (24 GB RAM) accelerator nodes.

Correct Answer: A

An Isilon customer is reporting less than expected performance from the cluster and poor space utilization. The customer is using three X400 nodes with N+2:1 protection policy to host webserver log data. Upon further analysis, it is discovered that the webservers write log files 64 KiB in size. The log files are then accessed by an analytics application for reporting.
What should be done to increase write performance of the cluster?

1. A. Change the protection scheme to a mirroring policy.
2. B. Add A-Series performance accelerator nodes to the cluster.
3. C. Add S-Series storage nodes to the cluster.
4. D. Add SSDs to the X-Series nodes in the cluster.

Correct Answer: A

An Isilon customer has two 5-node clusters, one for production and one for disaster recovery (DR). The customer's workflow is a SmartLock workflow and is replicated to the DR cluster through SyncIQ on an individual schedule. The customer needs to shutdown their production cluster for scheduled maintenance.
Assume both clusters have identical shares, exports, user authentication, and that the client applications have been stopped and the DNS re-pointed. What is the correct method to start operations on the DR cluster?

1. A. Initiate Manual Failover of the SyncIQ Policy
2. B. Initiate Automated Failover of the SyncIQ Policy
3. C. No change to the SyncIQ Policy
4. D. Revert the SyncIQ Policy

Correct Answer: B
